Answer:
Step-by-step explanation:
has the following properties:
º = 1.75 π (π = 180º)
therefore, z₁ = 13 * [ cos(1.75 π) + i sin(1.75 π) ] = 13*[cos(1.75π - 2π) + i sin(1.75π - 2π)] = 13*[cos(-π/4) + i sin(-π/4)] {this is due to periodicity} = 13*(√2/2 - i √2/2) = 
4/14 = x/63
14x = 4*63
14x = 252
x = 18 dress shirts
Check
4/14 = 0.286
18/63 = 0.286
